Fireweed Begins Field Work at Macmillan Pass

and appoints new CFO

Vancouver, British Columbia: FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ)

is pleased to announce that field crews have been mobilized and field work has begun on the Macmillan

Pass Zinc Project in Yukon, Canada, and that the Company has appointed a new CFO.

Macmillan Pass Project Work Program

Field work has begun on the Macmillan Pass zinc-lead -silver project. Building on the success of its first

exploration season last year followed by a new M ineral Resource report and a PEA economic study,

Fireweed plans to complete an $8 million exploration program on the project in 2018. The planned work

and main goals of 2018 work program are as follows.

Drilling Plans

A large 10,000 met er drill program carried out by three drills is planned to begin in the coming weeks

with three main goals:

• Expand known zones through step out drill holes to build tonnage beyond the already substantial

Mineral R esources (see Fireweed news release dated January 10, 2018 for details); all zones

remain open for expansion

• Upgrade priority zones to Measured and Indicated categories to de-risk key parts of the M ineral

Resources

• Drill new exploration targets toward discovery of entirely new deposits on the large land package

Details and sections for some of these drill targets are illustrated in the current Company presentation at

www.FireweedZinc.com .

Exploration for New Discoveries

Over the past year Fireweed acquired control of almost the entire Macmillan Pass Zinc District , a 470

square kilometer land package. This is also the first time in more than 25 years that any large scale

exploration program has been carried out in the district. Utilizing state of the art exploration techniques,

Fireweed will carry out a major exploration program in search of new deposits over this large land

package with drills readily available to test any new discoveries this year.

The 2018 field exploration work is being driven by modern exploration concepts a nd will utilize

extensive geological mapping, prospecting, geochemical surveys (stream sediment, soil and rock

sampling surveys), ground gravity surveys , and topographic surveys (airborne Light Detection and

Ranging ( LiDAR) and ground Differential GPS (DGPS) surveys). In all , a crew of about 45 persons

(including drillers) will be in camp to carry out the large work programs.

Permitting

Baseline environmental work is continuing and expanding on the project including water sampling and

monitoring, drill site and road reclamation, environmental fuel tank installations, and health and safety

improvements to the camp and project living infrastructure. This work has the aim of upgrading

environmental and living standards on the project site, and to accelerate permitting toward potential future

mine production.

Field work (geological mapping, geochemical sampling and test geophysics) as well as environmental

water sampling and other permitting related surveys have begun. Drills are expected to arrive on the

property in the coming weeks once the access road has been opened for traffic pending small post -winter

road repairs.

Brandon Macdonald, CEO, stated “Fireweed has made extraordinary progress since its IPO one y ear ago

culminating in the recently published PEA economic study and with a healthy treasury to fund this

aggressive exploration program, we are now taking the next big steps toward expanding and upgrading

Mineral Resources and making new discoveries.”
